Construction

Snowy 2.0 will significantly increase Snowy Hydro’s existing pumped hydro capabilities. The Project will link the two existing Snowy Scheme dams, Tantangara and Talbingo, through underground tunnels and an underground power station with pumping capabilities.

Snowy 2.0 will increase the generation capacity of the Snowy Mountains by up to 2,200MW and at full capacity will provide approximately 350,000MW/h of energy storage. It will be one of the largest pumped hydro schemes in the world.

Future Generation will deliver all activities associated with the civil works requirements for the pumped hydro-electric power station and associated infrastructure between the existing Talbingo and Tantangara Reservoirs which are in the Kosciusko National Park in NSW. Tantangara and Talbingo will be linked by 27km of power waterway tunnels. The power station will be located about 800m below ground.

Construction Key Facts

Snowy 2.0 is expected to comprise approximately 50 km of tunnels, adits and shafts. Most of the Project’s facilities will be underground but additional roads are required to access the underground power station, surge tanks along the power waterway and intake structures at both ends of the power waterway. This includes roads leading to the portal of the main access tunnel, a road to the emergency egress, cable and ventilation tunnel and cable yard and service roads leading to the surge tanks and the Tantangara and Talbingo Reservoirs intakes structure.
